This invention, in the embodiment at present preferred as best illustrating the principles involved, is adapted for use as a'forming press, but various other adaptations are contemplated, and the invention is by no means to be limited to the particulars of construction and operation of the embodiment herein shown and described for the purposes of the present disclosure. In this embodiment there is employed a] support comprising an enclosing and supporting frame 15 having an upwardly extending portion 16 provided with a head'17 carrying work engaging or operating devices which in the present instance are dies 18, With which cooperate a plurality of's imilar' 0 p era-ting devices or dies 19 on a movable element,'or, more specifically, a rotary carrier,

indicated generally at 20 and comprising a table which is intermittently rotated to bring the devices thereon successively to position for cooperation with the devices carried by head 17 The latter projects over the table for this purpose and mechanism is provided, as will appear later, for'eifecting relative movement of the device'son the head and table thus brought to cooperating position, toward and from each other, for operation on the interposed work.

Referring more particularly-to Figures 3 and 4 the carrier table is indicated at 21,

supported preferably on a frame 22 having" a sleeve-23 fixed on a main rotary element or shaft 24 rotatable in bearings 25 and 26, supportedby cross members of the main frame or support 15. 1

Carrier frame 22 is preferably provided on opposite sides with guide channels 27, ure 7, in which are-vertically movable crossheads 28, each carrying on its upper portion one or more of the operating devices 19 and formed at its lower portion with a projecting lug29 formed with an opening or bore vwith whichis threadedly engaged an oper-- ating rod or bolt 30 adjustable on the crosshead by reason of its threaded connection therewith and having a nut31 for locking the bolt in adjusted p'ositiona Across brace j 32 is fixed on each channel 27 and provided with a portion 33 embracing the correspondl ing bolt '30 for engagement with its headportion 34 to limit the downward movement thereof and of the cross-head, the purpose of this rod being to provide an operating means for raising the cross-head and the operating devices carried thereby for operation on the Work.

The operating mechanism for the Work engaging devices preferably comprises also a bearing sleeve 35 carried by the frame below the Work engaging devices in which bearing is longitudinally movable a thrust rod or plunger 86 having at its lower end a yoke 37 in which is .journaled a roller 38' cooperating With the surface of a cam 39 fixed on the upper side of a substantially disc shaped part 40 fixed on a sleeve 41 rotatabl-e on the main shaft and supported at its lower end by collar 41. Attached to the upper end'of sleeve 41 is a worm Wheel .42 meshing With a Worm 43' fixed on a shaft 44 rotated by mechanism hereinafter de scribed, which lmparts to sleeve 41 and the parts carried thereby continuous rotation about an axis concentric with 'the rotary main shaftand carrier. Disc 40 has an annular bearing flange 45 which rolls during the rotation of the-disc on a thrust bearing comprising a roller 46 journaled on a bra'clc et 47 supported on the main frame, and it will be'obvious =from the latter construction that as disc 40 is rotated, cam 39 carried sthereby serves to actuate plunger 36 longitudinally-for' cooperation with the lmvenend of bolt 30 to raise the-operating devices for operation on the Work, the thrusting stress of these parts being supported by bearing roller 46 which at all timeS engages the'under surface ofthe disc. It is apparent that these parts, as shown'in Figure 4, are substantiall-y in alinement With each other so that (the stressesoperate in astraight linebetiveen the bottom of theframe and head. 17 supported thereby, affording a compact substantial and ruggedtype of construction capable' of exerting very considerable pressure on the Work-without deformation or brealc age of the parts.

Positioningmechanism is provided for intermittentlyrotating the carrier or ivorlitable 21 to bring the devices caiu' edthereby successively to position beneath the operat-' ing device carried by thehe ad for cooperation With the latter, this mechanism c01nprising preferably a roller 48, Figures 4, 5 "and 9,-eo-acting With a Geneva gear rotatablysupported on shaft EOQFigures 3, 5 and :9, carriedin abe'aring l-at the bottom of the frame. This gear is preferably formed With'radial' channels52 adapted to receive roller 48 yvvhich' during rotation of disc 40-engages with one oftiiesechannels and rotates the gear through angle of approximatelvv 90 degrees, the *gear "being "formed between fthea'djacent channel entrances with curved portions -co-acting source of With a hub 54 on disc 40 to lock the gear against rotation, except when actuated by roller 48 opposite which the hub is vformed with a depression 55 forming clearance for the projecting part 56 of-the gear during such actuation. Connected With Geneva gear 49 and also on the shaft 50 is a spur gear 57 meshing with a gear 58 fixed on main shaft .24, by means of which the rotation of the Geneva gear rotates the main shaft and table 21 to bring the operating devices on the latter successively to position for coo oration with the operating 'deviceson t e frame, the table being locked by the Geneva motion between such intermittent rotation. Ts ith the present arrangement of operating devices on table 21 gears :57 and 58 have a two-to one ratio so that the table is rotated at each actuation "through approximately 180 degrees.

A centerin means is rovided for securbracket 61 fixed on the yoke 37 at the-lower end 01 the operating plunger36 Cooperat ing With spindle 60 area pair 01": brackets .62, one-on each side'of the carrier and each formed with a socket to receivethe spindle these parts being so arranged that the spindle engages one of the sockets just prior to upward actuation of theoperatingdevices ofthe 'WOlli table thereby centering-tlie latter during cooperation WltlltllG wvork'enga'g ingdevices on theframe. 7

"The actuating mechanism itor imparting continuous rotation to sleeve 41 on 'th'e main shaft comprises, in addition to sleeve 41 and its associated parts, the shaft 44, previously described, Which is and is'driven by the usual or any suitable system of'a change speed gearing located "in the casing 64., FigureS, and'controlled by means of a handle 65, this gearing hoi gver and requiring no "further description. A shaft 66 isv provided for actuatingthe'latter gearing and is driven from any suitable power, a pulley 67, FigureQjbeing shown in the present instance "for this purpose. It is apparrent that as sleeve 4l is continuously driven the Geneva motionde scribed 'rotatesthe main shaft intermittently to bring the Work engagingde'vices on table 21 successively ito with similar devices on the framea ndcenjournaled in a bearing 63' position *for cooperation ters and locks the table "in such position for a brief period during Whichc am39 raises plunger '38, and iconsequently'the 'crcsjsEhead "and operating devices carried thereby, "for operation on thework. After each such operation the cross-head and \v0lrl*-engaging devices are loweredfand the carrieFun;

locked and subsequently rotated to bring the succeeding pair of operating devices to position to repeat the operation during which the opposite devices are Conveniently stationary at'the front of the work table for the placing'of the Work thereon. The work may therefore be safely and expeditiously locatedon the table, in proper relation to the operating devices or dies, without requiring the operator to place his hands in the neighborhood of the active or cooperating dies,

so that all danger of injury thereby is obviated.

Various operating devices may, of course, be employed with the resent machine and are preferably detacha ly and interchangeably secured thereto by the usual or any suitable arrangement known to the art, the 7 devices shown in conjunction with the present embodiment being dies mounted in pairs for "accomplishing a forming or'doming operation on' a paper or fabric receptacle,

- and in performing such work it is at times desirable to provide means for heating the "dies in order to render the work soft and 'wpliable' to facilitate the shaping operation.

Accordingly the dies 19 on the work bed rings-72uwith which are connected wires 73 l passing upwardly through a conduit 74 supported by a-bracket on the head 17 Similarly the dies 18 on the frame are provided with heating means 7 5 to'which current is supplied through wiring? 6. i

To facilitate the heating act-ion of the dies cam 39 is provided with a profile compris inga rise 77 effecting a preliminary movement of the dies into proximity with the a work, wherewthey are permitted to remain .for a short period by a flat portion ordwell 78 on the cam, the diesbeingsubsequently raised and pressed against the heated work .to form the same by: the elevated portion 79 of the camf, In this manner-the dies are firstfmoved into proximity to the work where they remain long enough to heat and 1 V v1.

WVhile one series of dies on the work bed is thus in operation, another series 'is at rest at'the front of the bed so that'the work may be-conveniently, rapidly and safely located on such dies in preparation for subsequent The work is placed by the operator operation on it. As each series o'f.-'d1es'-is I moved from operating position toward the front of the machine the completed work may thus be removed and new ,workbe substituted or if desired; thecompleted work may be automatically removed by a stripping device such as is well known in the art."

Various forms of operatingfl'devices or of dies may be employedin the machine,"the

'.parts forfsupporting such devices being adjustable to accommodate their varying d1.-

'mensions. The operating parts areclurable' in construction and positive 'in operation and the'arrangement of the partsis such as toafford an exceedingly compact and strong construction. The arrangement of sleeve 41 and associated parts of the actuating means or mechanism in the substantially unitary and compact formdisclosed concentric with the main rotary element orcarriershaft24: materially reduces the number of parts and the size and Weight of the machine.
